Comparing two decks

What happens to my odds if I change the deck? Add two lands, cut a spell, does the opening hand get better?

Turn on alternate deck in Input settings and the card table grows a second deck column, with a [+ deck] button or a delete control on each deck column. The card rows and the hands are shared between decks, only the deck counts differ.

Alternate decks

Each deck reports its own result and its own running total, and the chart draws one line per deck on a shared axis. Export and import work with both decks, so a saved decklist keeps the comparison.
